摘要： A computer implemented method, apparatus, and program product for extending virtual memory associated with logical partitions. A hosting partition receives a paging request from a logical partition on a logically partitioned data processing. The hosting partition identifies a location of the physical memory space on a remote computing device assigned to the logical partition and sends an extended virtual memory paging request to an extended virtual memory manager located on the remote computing device using a network connection. The extended virtual memory paging request comprises the instructions for the memory page-in or the memory page-out and the location of the physical memory space on the remote computing device that is being paged-in or paged-out. The extended virtual memory manager performs a page-in operation or a page-out operation in accordance with the instructions for the memory page-in or memory page-out.

摘要： A method, system, and computer program product provides effective management and deployment of image files within a Virtual Input/Output (I/O) Server (VIOS) cluster. An Image Management (IM) utility utilizes a discovery process to establish connections with objects in order to manage these objects. Following discovery of an ICP client, the IM utility enables creation of a virtual server partition and initiates the importing of a captured image to a VIOS cluster Storage Pool (SP). The IM utility creates logical units (LUs) within the Image Management Fileset (IMF) for each file within the captured image. The IM utility maps the LUs to the VIOS Cluster SP using unique image file handles. The IM utility configures the new storage that comprises the created LUs. The IM utility copies image files to the appropriate storage device/LU. When import/copy of the image is completed, the IM utility activates the virtual server partition.

摘要： A method, data processing system and computer program product provide scalable data synchronization for a virtual input/output server (VIOS) cluster and one or more registered callers. A first VIOS is commits as a primary node of the VIOS cluster and performs the functions of: registering one or more callers to receive notification from the first VIOS of specific events occurring within the cluster; receiving notification of an occurrence of one of the specific events; and in response to receiving notification of the specific events, a deamon of the first VIOS retrieving a message payload file from a message payload file directory within the shared VIOS DB and passing the message payload file to the API, which forwards/posts the relevant event notification information from the message payload file to the TCP socket of each registered caller.

摘要： A method, data processing system, and computer program product autonomously migrate clients serviced by a first VIOS to other VIOSes in the event of a VIOS cluster “split-brain” scenario generating a primary sub-cluster and a secondary sub-cluster, where the first VIOS is in the secondary sub-cluster. The VIOSes in the cluster continually exchange keep-alive information to provide each VIOS with an up-to-date status of other VIOSes within the cluster and to notify the VIOSes when one or more nodes loose connection to or are no longer communicating with other nodes within the cluster, as occurs with a cluster split-brain event/condition. When this event is detected, a first sub-cluster assumes a primary sub-cluster role and one or more clients served by one or more VIOSes within the secondary sub-cluster are autonomously migrated to other VIOSes in the primary sub-cluster, thus minimizing downtime for clients previously served by the unavailable/uncommunicative VIOSes.

摘要： A first virtual I/O server (VIOS) provides a cluster aware (CA) operating system (OS) executing on a processor resource of the first VIOS to register the first VIOS within a VIOS cluster. The first VIOS comprises a first field/failure data capture (FFDC) module that executes within the first VIOS and performs the functions of: receiving from an event listener a signal indicating that an FFFDC event/condition has been detected by the first VIOS; and automatically transmitting FFDC data to the shared storage repository for storage of the FFDC data within the shared storage repository. The FFDC module further performs the functions of: transmitting to one or more second VIOSes within the VIOS cluster, one or more messages to inform the one or more second VIOSes of an occurrence of the FFDC event/condition that was detected by the first VIOS.

摘要： Hibernation and remote restore functions of a client logical partition (LPAR) that exists within a data processing system having cluster-aware Virtual Input/Output (I/O) Servers (VIOSes) is performed via receipt of commands via a virtual control panel (VCP) through an underlying hypervisor. The client hibernation data file is stored in a shared repository by a source/original VIOS assigned to the client. The hypervisor receives a remote restart command and assigns a target/remote client LPAR and a target VIOS. The source I/O adapters and target I/O adapters are locked and the target VIOS gathers adapter configuration information from the source VIOS and configures the target adapters to be able to perform the I/O functionality provided by the source adapters to the client LPAR. The target VIOS then retrieves the client's hibernation data file, and the client LPAR is restored at the remote LPAR with the target VIOS providing the client's I/O functionality.

摘要： In a data processing system having a plurality of virtual input/output servers (VIOSes) configured within a VIOS cluster, a method, data processing system and computer program product provide for autonomous election of a primary node within a virtual input/output server (VIOS) cluster. A first VIOS performs the functions of: detecting that a primary node is required for the VIOS cluster; and autonomously initiating an election process to elect a next primary node from among the VIOSes within the VIOS cluster. When the first VIOS meets the pre-established requirements for becoming a primary node, the first VIOS obtains a lock on a primary node ID field within a VIOS database (DB) and then initiates a primary node commit process to assign the first VIOS as the primary node. The first VIOS issues a notification to the VIOS cluster to notify the other VIOSes that a primary node has been elected.
